Their are 4 basic groups of Ceramic Coatings.
Excessive temperature can lead to metal fatigue, boiling fluids damaging metal expansion and more. These coatings allow the metal to transfer heat away 20-30% more efficiently. They are also oil shedding, providing faster drain-back to the oil pan. Use them on any part that is or can be used to provide cooling. Radiators, AC condensers, heater cores, intakes,supercharger/turbo inter-coolers, inter-cooler piping, etc.
These coatings reduces the ability of heat to escape from the applied part or protect a part from excessive heat. In combustion chambers you want to use the heat generated by combustion to push down on the piston rather than bleed off into surrounding surfaces. These coatings can also provide oil shedding properties. A Thermal barrier applied to exhaust runners keep the heat of exhaust gasses from soaking the head which in turn helps the cooling and moves the heat out the exhaust, this coating also improves the flow through the head. This same coating applied to intake runners in diesel motors improves air flow while helping the air charge stay cooler thus improving power. The back side of break pads coated with a barrier will slow the transfer of heat to the caliper piston in turn keeping the break fluid cooler.
DRY FILM LUBRICANTS
Also known as solid film lubricants, these coatings can be applied to any surface that experiences sliding or rotational friction. The interesting property with these coatings is that they are also oil retaining, meaning; they not only provide lubrication by themselves, but also help hold oil to the part for even better lubrication. These coatings may also allow lighter weight oils to be used, thus freeing up horsepower.
These coatings are most commonly used to provide a more attractive appearance to a part. Many of the coatings in this area also provide increased protection against corrosion and are very chemical resistant.
CERAMIC COATINGS THICKNESS
Ceramic coatings are based on thin film technologies. Finished thickness is typically 1 mil (.001”). Most ceramic dry film coatings burnish down to a final thickness close to 0 tolerance.
Ceramic coatings will withstand temperatures in excess of 1600°f with some formulations good beyond 2000°f.
